Rahul,both tools are built on the same technology foundation and both therefore are able to create and run jobs or big data workloads.Where they start to differ is as follows:

with Enterprise Edition you require to define, manage and operate your deployments yourself but therefore have full controlwith Integration Cloud offers a managed service and you are not burdened with the deployment aspects

Integration Cloud also addresses new use cases over the Enterprise Edition. You can choose from prepacked integration patterns which are found on Talend Exchange and the user can then quickly assemble its own integration flows. With Talend Studio you can build your own patterns and make it available to the cloud user.For further information feel free to ask more questions here or contact me directly.
